Rewrite conflicts - Wordpress plugin hell :(

Although I managed to get an internal cosmos and tagging thing working last week I seem to have run into a rewrite rule conflict due to my choice of wordpress plugins. The feedburner plugin I installed a few weeks ago uses mod_rewrite to pass all requests for RSS feeds, regardless of the format, over to the feedburner URI. As the tagging plugin is also rewriting the URLs this causes problems. I'm not sure how I can fix this one, but I may be able to come up with some kind of hack. I think I need to spend some time reading up on mod_rewrite and .htaccess :(
